Our grammar currently parses modules inside functions just fine. However, it
doesn't look like it's possible to call any functions defined in one. For
instance:
fn main () {
use z;
mod z {
fn f () -> int { 19 }
}
z::f();
}
Note that the "use" has to be at the beginning of the block--that's enforced.
This gives the error:
/tmp/foo.rs:2:8: 2:10 error: failed to resolve import: z
/tmp/foo.rs:2 use z;
^~
error: failed to resolve imports
error: aborting due to 2 previous errors
It looks to me like modules are allowed here just because it's consistent with
allowing other item types--struct and enum decls, for instance. Am I missing
something obvious? In particular, I'm bad with the resolver; perhaps there's a
way to write the "use" to make this work. If not, it would seem to me like
removing them would be the sensible choice.
Thoughts?
